Property Value

Type Description
AutoCreateOption

An AutoCreateOption enumeration value that specifies the action which is performed when a data store is accessed for the first time.

Available values:

Name Description
DatabaseAndSchema

A session will try to automatically create the database if it doesn’t exist. It will also create or update the database schema for any persistent classes currently being used.

SchemaOnly

A session will automatically create or update the database schema for the persistent classes currently being used. If the database doesn’t exist, it won’t be created by a session.

None

A session will not automatically create the database or update the database schema. The database schema is still queried and checked to match the currently used persistent class metadata.

SchemaAlreadyExists

A session will never query the database for schema to validate against persistent class metadata. This will suppress the SchemaCorrectionNeededException, but a database error may occur during data operations if the schema is not compatible with run-time persistent classes metadata.
